You would normally add the baking soda in front of a return flow in the deep end, though it was OK to add it to the skimmer if done slowly. You didn't list your Calcium Hardness (CH) level. If it's below 100 ppm, you can raise it to 100 to 150 ppm to prevent foaming in general.

Are you sure you added Arm & Hammer Baking Soda and not the laundry detergent? Are you sure that your TA was really as low as 30 ppm? That seems VERY unlikely if your CYA was 80 ppm and your pH was 7 (7.0?). Are you using a good test kit such as the Taylor K-2006 or the TF100 from tftestkits(dot)com?

The foam has pretty much gone away, still minimal foaming when kids acting like kids but nothing like last night. My ph and TA went up with just arm and hammer baking soda (not laundry detergent), so Im putting borax up for a future time.

The water is clear but in the 9 foot end its not "crystal" clear, very little hazing. I am losing NO cl thru the night. I think Im ok, but due to the not crystal clear issue I did put 2 gallons of bleach (5.25%) in it for the evening...if nothing else to just be safe.

I will assume the foaming and all is norm when you put the A and H in the skimmer side instead of on a sock at the outlet. If you can let me know I will live.

I think Im going to try and keep the chlorine level at 8 for the rest of the summer, the thought of algea bloom sickens me to be honest.
